# 7-bit command sweep notes
|
||||
|
||||
## Revised protocol (after sweep)
|
||||
|
||||
Layout: `PPP M BGR` (7 bits, MSB first). Same pulse timing as before.
|
||||
|
||||
| Field | Bits | Meaning |
|
||||
| ------- | ------ | --------- |
|
||||
| PPP | 3 | Pattern (8 modes — not 4) |
|
||||
| M | 1 | Palette / multi flag |
|
||||
| BGR | 3 | Color or palette select |
|
||||
|
||||
The old write-up treated this as `0 PP M BGR` (leading bit always 0 + 2 pattern bits). The leading bit is actually **pattern bit 2**; the app simply never used patterns `100`–`111`.
|
||||
|
||||
### Patterns (`PPP`)
|
||||
|
||||
| PPP | Name (working) | Behavior |
|
||||
| ----- | ---------------- | ---------- |
|
||||
| `000` | Steady | Solid color / palette |
|
||||
| `001` | Fade | Fade (OEM “Fade”) |
|
||||
| `010` | Sparkle | Sparkle to white (OEM) |
|
||||
| `011` | Firefly | Firefly (OEM) |
|
||||
| `100` | Twinkle | Mostly off; random bulbs flash on in color (colored sparkles on dark) |
|
||||
| `101` | Fast sparkle | Like Sparkle but faster |
|
||||
| `110` | Anti-sparkle | Base color on; sparkles turn bulbs **off** (black sparkles) |
|
||||
| `111` | Fast twinkle | Faster version of Twinkle (`100`) |
|
||||
|
||||
### Color / palette (`M` + `BGR`)
|
||||
|
||||
When `M=0`, `BGR` is a normal solid color (same as before):
|
||||
|
||||
| BGR | Color |
|
||||
| ----- | ------- |
|
||||
| `000` | Off |
|
||||
| `001` | Red |
|
||||
| `010` | Green |
|
||||
| `011` | Yellow |
|
||||
| `100` | Blue |
|
||||
| `101` | Magenta |
|
||||
| `110` | Cyan |
|
||||
| `111` | White |
|
||||
|
||||
When `M=1`, `BGR` selects a **palette** (not a single RGB mix):
|
||||
|
||||
| BGR | Palette |
|
||||
| ----- | --------- |
|
||||
| `000` | Classic multi (per-bulb random across colors) |
|
||||
| `001` | Christmas — red / white / green |
|
||||
| `010` | July 4th — red / white / blue |
|
||||
| `011` | Same as classic multi (indistinguishable from `000` in testing) |
|
||||
| `100`–`111` | Often **off** or pattern-dependent (see tables; Fade/Firefly sometimes treat these as solid B/M/C/W) |
|
||||
|
||||
Palette behavior depends on pattern (e.g. Steady+Multi+`1xx` → off; Fade+Multi+`1xx` → solid colors; Sparkle+Multi+`1xx` → dark with white sparkles).
|
||||
|
||||
### OEM / app subset
|
||||
|
||||
The phone app only used `PPP` in `000`–`011` with either solid colors (`M=0`) or Multi (`M=1`, `BGR=000`). Hidden: palettes `001`/`010`/`011` and patterns `100`–`111`.
|
||||
|
||||
---
|
||||
|
||||
## Known (skipped by early sweep sketch)
|
||||
|
||||
- `PPP` `000`–`011`, `M=0`, any `BGR` → published Steady/Fade/Sparkle/Firefly × colors
|
||||
- `PPP` `000`–`011`, `M=1`, `BGR=000` → Multi with those patterns
|
||||

|
||||
|
||||

||||
|
||||
### A) Multi + nonzero BGR (`PPP` `000`–`011`, `M=1`, `BGR≠000`)

||||
## Summary
|
||||
|
||||
- **8 patterns**, not 4 — high bit selects the alternate set (twinkle / fast sparkle / anti-sparkle / fast twinkle).
|
||||
- **`M=1` is palette mode**: `000`/`011` classic multi, `001` Christmas R/W/G, `010` July 4th R/W/B; `1xx` is pattern-dependent (often off).
|
||||
- Fade/Firefly + Multi + `1xx` oddly map to solid B/M/C/W — possible alias or shared decode path.
|
||||
- Names above (Twinkle, Fast sparkle, etc.) are working labels from observation, not OEM names.
